It's a drawing of a spade. The image looks like a spade that you would find on a playing card. The body of the spade is perhaps more prominent than the stem of the spade compared to a conventional spade drawing.
This Spades icon has Android KitKat style
. If you use the icons for Android apps, we recommend using our latest Material Icons icon pack (please check our sidebar on the right). Otherwise, it's a solid icon pack that looks good in small resolutions, either on the web or in print. It's characterized by thick lines, smooth corners, and is optimized for 24x24 pixels.
